The parking brake latch
arm, kick-off cam and
catch bracket are hard
ened parts. Do not grind or file them. New parts must
be used.

Inspect catch bracket and latch arm.
Replace if showing signs of wear or damage (Ref Fig.
12 on page M-10).
11.
Inspect the parking brake kick-off cam.
Look for wear and for correct adjustment. With the
parking brake engaged and fully latched, there must
be no gap between the top of the cam and the latch
arm. Adjust the kick-off cam (3) if required (Ref Fig.
12 on page M-10). It is very important that the correct
setscrews are used to hold the kick-off cam to the
pivot rod. Use of longer screws prevents correct
adjustment of pedal bumper (pedal travel) and may
prevent the brakes from adjusting properly.

Inspect kick-off cam linkage and bushings.
Check for wear and damage. The kick-off cam pivot
and bushings should move freely and be free of cor
rosion. The kick-off cam should rotate when the
accelerator pedal is depressed.
Periodic Brake Performance Test (PBPT)

WARNING.A.
of all personnel.
All brake tests must be
done in a safe location
with regard for the safety
Always conduct a visual inspection and evaluate ped
al travel before operating a vehicle to verify some
braking function is present
The Periodic Brake Performance Test (PBPT) should be
performed regularly (see Periodic Service Schedule in
the GENERAL INFORMATION AND ROUTINE MAIN
TENANCE section of this manual) as an evaluation of
braking system performance. It is useful as a method of
identifying subtle loss of performance over time and as
part of troubleshooting a problem vehicle.
Before performing this test, inspect the brake pedal and
linkage and correct any problems found including adjust
ing the brake pedal free travel if required.
The purpose of this test is to compare the braking perfor
mance of the vehicle to the braking performance of new
or "known to be good" vehicles or to an established
acceptable stopping distance (see below). Actual stop
ping distances will be influenced by weather conditions,
terrain, road surface condition, actual vehicle weight
(accessories installed) and vehicle speed. No specific
braking distance can be reliably specified. The test is
conducted by latching the parking brake to eliminate dif
ferent pedal pressures and to include the affects of link
age mis-adjustment. Significant changes or differences
in braking performance will be evident due to mis-adjust
ment.
Establish the acceptable stopping distance by testing a
new or "known to be good" vehicle and recording the
stopping location or stopping distance. For fleets of vehi
cles, several vehicles should be tested when new and
the range of stopping locations or distances recorded.

NOTE
I
Over time, a subtle loss of performance may
�---� take place; therefore, it is important to establish
the standard with a new vehicle.
Drive the vehicle at maximum speed on a flat, dry, clean,
paved surface (Ref Fig. 13 on page M-11). Quickly
depress the brake pedal to latch the parking brake at the
line or marker in the test area and remove foot from
pedal. The vehicle should stop aggressively. The wheel
brakes may or may not lock. Observe the vehicle stop
ping location or measure the vehicle stopping distance
from the point at which the brakes were latched. The
